To secure cheap flights from Detroit Metropolitan Wayne County Airport (DTW) to Ninoy Aquino International Airport (MNL) in March, book 6–10 weeks ahead and target midweek departures (Tuesday–Thursday). Use flexible-date search tools, set price alerts on multiple aggregators, and compare one-stop routings via hubs with frequent sales (e.g., Tokyo, Seoul, Taipei, Hong Kong, or Doha). Consider alternative nearby departure airports for better fares only if the added ground cost and time still make the itinerary cheaper overall. Look for airline promotions from Philippine Airlines, Japan Airlines, ANA, Korean Air, EVA Air, and alliance partners during late-winter sale windows.
Tips
- Book early in the booking window (6–10 weeks) to catch March fare drops.
- Fly midweek and avoid peak holiday weeks including Holy Week if it falls in March or early April.
- Monitor multiple OTAs and airline sites for flash sales and promo codes.
- Consider multi-city itineraries to combine Manila with Cebu or Palawan for potential savings.
- Use flexible date calendars and set fare alerts for Detroit to Manila routes.
